To all it may concern.'

Be it known that I JOHN W. Dnvms, va citizen'of the 'United States, residing at' Reading, in the county of. Middlesex and l State 'of Massachusetts, have invented an Improved Emulsier and Clarier, of which the following is e specification, reference being had to the accompanying drawings, forming part thereof.

This invention has reference to im 4rove- ,ments in machines for emulsifying mi' and other liquid or semi-li uid material,I which ina-chinois also ada tocllrify such Imaterial or othermore or less solid material having or com d of constituents some of which diier" s to specific gravity fromothers.- Onelobject of the invention isto provide an emulsiiier adapted to 'be econoniicall driven in which the material to be treats under pressure produced by* centrifugal ,ac-

tionhinay be forcedbetween'novel squeezin elements carried' by the container in whicg said centrifugal action isproduced.- Another object of the invention is. to provide machine of thisnature having a rota container furnished with a series of restricted outletsso constructed that a consid. arable body or quantity of comparatively heavy-material can, under centrifugal ac-` tion, be retained in said container while' l other material of comparatively lighterV weight can be forced b .y enfl'ifuiil'Pm-` sure through said outlets. IU Another'object of the invention iste im- \-v1ces.

. Other objects of the invention will froin'the following dcscri tion.

The invention conaists the rotary con tainer having the novel outlet units. The inventionalso consists in such other novel features of construction and combina; tion'of parts as shall hereinafterbe more. folli described and pointed outin the claims.

wall othead 21, the action of passing the material between these parts depending somewhat upon the adjustment of plugr element 24. Ordinarily these parts will he so adjusted that the fat globules of milk passing therebetween will be disrupted.

Mounted Qn the head 6 is the pan 29 having the downwardly inclined wall 30 furnished with the annular wall 3l having the outlet 32. Into wall 31 is received the. similar.' wall 33 of cover member 34 which has the flaring dcfiector 35 and the top 36 carrying the c amber 37 which is adapted to receine liquid to be treated and has the axially dis osed inlet pipe 38 which is slidable in a earing of said chamber 37, and

.extends through the opening in the guard 1f) of receptacle 16 'md is adapted to deliver material to be treated adjacent the bottom 17 of said receptacle 16.

In making use of this machine as an emulsifier the plugs' 24, are suitably ad` j usted in their casings 20, the receptacle 16 is caused to rotate at the desired speed and milk or other liquid to be treated is placed in the chamber 37 and passes through pipe 38 into said receptacle 16. Under centrit' ugal action caused by rotationof said receptacle the milk o1' liquid becomes banked against the. annular wall 18 and the 'heavier particles oi foreign matter are driven to- Wardsaid wall 18 and adhere to the film or layer of milk or liquid covering said Wall. 'As soon as-the body of milk or liquid adjacent the wall 18 becomes large enough' to cover the inwardly extending casings 20, and the pressure generated in said milk or liquid by centrifugal action is suiiicient the milk or liquid will be forced through the perforations 22, of casings 20, into the clean ances 28, of the plugs 24, and thence hetween the elements 27, of said plugs and the cooperating wall of head 21 and in such passage a lar proportion of the globules or. articles o .such milk or liquid will be bro en u or disrupted. The emulsion thus made wil thenV pass through the perforations 25,` of the. plugs 24,v and will be delivered into pan 2,9.v

'The defleetors23., prevent the direct-passage of the liquid in receptacle 16 to the outlets or perforations 22, so that such liquid reaches said outlets indirectly after the foreign matter has had an opportunity to pass toward-the wall 18 yand yat a' time `when the liquid is under considerable pres-` sure.

The. extension of the outlet units, comprising 'casings 20, inward from the wall 18 has the advantage that. la large body of impurities, foreign'niatter, or matter 'o any kind. and of sui-table specific .gravity may accumulate and he retained at or nearysaid wall 18 without-obstruetiug the perforations 22. This is particularly desirable when' the machine is used to clarify a material of the vnature of cocoa in which it is desired to retain the heavier cocoa constituents within the receptacle 16 and -to drive o'f the lighter oily constituents. In this case the crude cocoa is supplied to receptacle 16 and, by its rotation, is placed under centrifugal. action whereupon the heavier constituents are forced toward the wall 18 more rapidly than are the lighter constituents with the result that the former accumulate at the wall 18 while the latter may pass outward through the perforations 22, 22.

l-lavilng thus described my invention I claim as new and desire to secure by Letters Patent- An emulsifier or silnilar machine comprislng a rotary receptacle having a cylindrical liquid confining wall and one or more outlet units extending inward from said Wall whereby the outlet passages of said units are spaced from said wall.
